A survey was conducted of 100 people whether they have read recent issues of 'Golmal', a monthly magazine. Summarized information is presented below :
Only September: 18
September but not August: 23
September and July: 8
September: 28
July: 48
July and August: 10
None of the three months: 24
What is the number of surveyed people who have read exactly for two consecutive months?
Exactly two consecutive months include both July-August and August-September. We cannot include July-September, as these months are not consecutive.
      Â
N - none of the three months
Number of people who read in July and August only = 7
Number of people who read in August and September only = 2
Therefore, the number of surveyed people who have read exactly for two consecutive months = 7+2 = 9
Answer is option B.
